Botanical Name

BOLTONIA diffusa

Plant Common Name

Smallhead Doll's Daisy

General Description

Clouds of small white to lilac "daisies" adorn this medium-sized to large herbaceous perennial from late summer to early fall. It is native to prairies, woodlands, and roadsides in the south-central and southeastern United States.

Variable in height and habit, smallhead doll's daisy typically forms a tall clump of upright stems clothed in linear to narrowly lance-shaped leaves. Plants sometimes spread rapidly via underground stolons. Yellow-eyed "daisies" appear in large airy clusters for many weeks beginning in mid-to late summer. The blooms attract many pollinators such as butterflies and bees.

Full sun is best for this tough, adaptable, and cold-hardy perennial. It succeeds in many soils, from poor and dry to fertile and moist. Plants may flop in rich soil or partial sun, requiring staking. Forms with stolons may invade neighboring plants.

This United States native is ideal for wildflower and butterfly gardens.
